Question

If an input force of 202N is applied to the handles of the wheelbarrow in the sample problem how large is the output force that just lifts the load?

Answer 1

For this case, the relationship between the two forces is given by:

F1 = nF2

Where,

• F1: output strength
• F2: input force
• n: mechanical advantage

Then, replacing the values we have:

F1 = (2.2)(202)

Having the calculations we have:

F1 = 444.4N

Answer: The output force that only lifts the load is F1 = 444.4N.
